Abstract Effect of acupuncture at Nei-Kuan (EH-6) on left ventricular ejection fraction (LVEF) was examined in 22 patients with angiographically proved coronary artery disease (CAD) and 22 normal subjects. Serial equilibrium radionuclide angiography was done to measure LVEF at 4 different times (at baseline, at 1 to 15 minutes, and 16 to 30 minutes during acupuncture, and immediately after acupuncture). One week later, each patient had an identical imaging protocol with acupuncture performed at a dummy point. Our results showed that in normal subjects, the mean values of LVEF did not change significantly during or after acupuncture. In contrast, in patients with CAD, the mean values of LVEF in the initial 15 minutes of acupuncture significantly increased from baseline (42.5 +/- 15.6\% vs. 40.6 +/- 15.4\%, p < 0.05). The increase persisted through the next 15 minutes of acupuncture and 15 minutes after acupuncture, but became insignificant at one week. Thus, acupuncture at Nei-Kuan can temporarily improve LV function in patients with CAD.
